IMPROVED CARPENTERS BENCH-GAGE.

Specification ibrming part of Letters Patent No. 36,973, dated November 1H, 1832.

To all whom it may concern:

Be it known that I, FREDERICK A. TEAUT, of New Britain, county of Hartford, and State of Connecticut, have invented certain newand useful Improvements in Carpenters Bench Gages; and I do hereby declare that the same is described and represented in. the following specification and drawings; and to enable others skilled in the art to make and use the same, I will proceed to describe its construction by referring to the drawings, in which the same letters indicate like parts in each of the figures.

This improvement consists in making the bar proper in two 0r more parts of about equal dimensions, each part-being provided with a tooth at the point of the commencement of measurement, and from that point is marked off inches and fractional parts of inches. The two or more bars are also fitted together, in most cases, with tongues or grooves, or otherproper mechanical means, and ltted to the head, and each separately secured in its proper place by means of thumbscrews, so that the workman has only to set, rst, one tooth to the width desired, and then another to the thickness; or, if it is desirable to set the gage for a tenon or mortse, it may be set in the same way. I propose sometimes to place the teeth in the sides and the scale of inches and fractional parts ot' the same on the edges, especially for gaging mortises and tenons.

In the accompanying drawings, Figure l is a side view. Fig. 2 is an end view showing the bars c working together by means of a tongue and groove, a a.

b are the gage-teeth. c is the gage-head. d are the set screws for holding the bars in the desirable place. In the common or ordinary way, where the slide is cut into the single bar, they are very liable to get out of order and frequently become useless, and thereby ren` dered very perplexing to the workman to put it in proper shape for use. By this improvement such difficulty is overcome, and a cheaper and more desirable article produced.

I claim- As an improved article of manufacture, a carpenters bencligage-viz., thc two or more bars e e, held in uniform position by means of tongue and groove a a', or their equivalents, in combination with asingle head, c, and set-screws d d, substantially in the manner as described.
